To all whom it may concern:

Be it known that I, Fnrrz Koon, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesot-a, have invented certain new and useful Improvements in LoadMoving Apparatus, of which the following is a specification.

My invention relates to improvements in load-moving apparatus designed particularly for moving hea machines such as derricks and steam shove s, but adapted for use with any load-supporting frame carrying a shaft and power to turn it, the object of the invention being to provide simple and efficient means for lifting and moving a load-carrying frame by the use of its own power:

To that end the invention consists in the construction, combination and arrangement of arts hereinafter described and claimed. 11 the accompanying drawings forming part of this specification, Figure 1 is a perspective view of the invention applied to a s aft-carrying frame, the shaft-actuating means being omitted for the sake of clearness. Figs. 2 and 3 are front and side views, respectively, of a slightly modified construction of the eccentriehfting pin, and web.

Fig. 4 is a diagrammatic .side view of the frame and carriage showing the same in nor- I lsaskeletoncuriagecof ygreater Upon the outside of each wheel mal position, both resting upon the ground. Fig. 5 is a similar view showing the frame in up-raised position; and Fig. 6 is a similar vlew, but with the carriage in up-lifted position, and showing means for actuating the shafts of the frame, For the sake of clearness and simplicity I have shown the invention apglied to a simple frame A ca ing an engine but it will be understood t at 'the invention is ap licable to any sort of frame, whether part 0 a machine or not, which carries a driven shaft and meansto drive it.

As shown in the drawings, the frame has two shafts 2 supported in bearings 3 upon the frame and carrying at each end a wheel 4. is detachably secured, by bolts 5 or otherwise, a plate or disk 6 carrying a lifting pin 7 arranged eccentrically to the shaft 2 and parallel therewith. The web between the shaft and pin thus constitutes a crank, and'for convemence the pinI 7 may be called a crankin. In Figs. 2 and- 3 the pin and "plate are sffown as a steel cast-- ing with raised tread of the whee Cooperating with the sup ort' .frame A anisrn, such wleb 8 extended beyond the length and width than the frame to permit the frame to work within it Arranged upon the sides of the carriage in position to receive the eccentric liftingpins 7 are skeleton bearing-frames 9 having at top and bottom interior bearings 10 and 11, respectively, with preferably divergent sides for the lifting pin 7.

n alternately lifted as hereinafter explained, the bearings are spaced apart a distance less than twice the throw or radius of the crank. It will be observed that the frame A extends down below the shafts 2 to form a supporting base 12 to bear upon the ground and enable the carriage G to be lifted upon it, and that the lower bearing 11 of the frame 9 is positioned at such height that the lifting pin 7 wil stand out of vertical alinement with the. s aft 2, when the frameand carriage are at rest upon the ground, asshown in Fig. 4. v jflhe shaft through the medium ofany appropriate mech asthe gears 13 and 14 carried, respectively, by the drive shaft 15 of the engine and one of the shafts 2, these gears meshing with an intermediate gear 16. The shafts 2 may be operatively connected, as for instance by the sprocket wheels '17 and chain 18, or such connection ma be dispensed with, oneonly of the shafts eing driven.

It will be observed that shown in the drawings have no function except to form a tion between the shaft and crank-pin.

of themselves crank conneclifting pin or I have shown this, however, as

wheels 1 are usually to be found upon the particularly adapted, and they can be readily used as cranks by bolting carrying disk such as is shown in Figs. 1, 2 and 3. After the machinehas been moved to the desired place-the disks may be removed and used on other machines. The construction of the carriage as here shown, with theside bars arran ed outside ofthe wheels of the frame, makes it particularly well adapted for use upon a steam shovel or other heavymachine, because the side bars form a Wide base for the machine to rest upon and ive it more stability than if it rested simp y upon its own wheels. The side bars thus serve to take the place of jacks, which are commonly used upon such machinesto n heavy work.

heavy machines for which my invention is to them a pin' take up the side thrust and tosteady them i order that the frame and carriage may be 2 may be driven from the engine the wheels 4 I my preferred form of crank because such" the machine will be In operation, when the carriage and frame are at rest they will assume the positions shown in Fig; 4, both carriage and frame resting upon the ground; When the shaft 2 is turned right-handedly the pin 7 will be thrust against the lower bearing 11 and force the shaft and frame to rise up and move forwardly around the pin in the arc of a circle of which the pin is the center, as shown in Fig. 5, until the frame descends with its shaft on the other side of the pin, the. distance of its forward travel depending upon the distance between the bearings andthe length of the crank. As the shaft continues to revolve the'pin will be turned until it lodges against'the upper bearing 10, when it will lift the carriage and move it circularly forward, as shown 1n Fig. 6, until it descends againwith the pin on the other or forward side of the shaft. By continuing-this alternate lifting and moving of frame and carriage made to wal ahead by its own power until it reaches the desired destination.

It will be evident thatwhere onlythe forward shaft 2 is driven, only the forward end of the frame and carriage will be lifted and rest on the ground, a carriage which rests on wardly; substantial moved in the manner described, the other end being merely drag ed along the ground.

Changes may be ma e in the details of the device without departing from the principle of the invention, the scope of which is defined in the claims.

I claim as my invention:

1. An apparatus of the character described, comprising a carriage having side rails, a frame provided with a horizontally disposed rotatable shaft, and cooperating means on'said shaft and on the side rails of the carriage for causing both the frame and carriage to be alternately raised bodily from the ground and moved forwardly as the shaft revolves; substantially as described.

' 2. 4 An apparatus of the. character described, comprisinga frame rovided with a horizontally disposed rotata le shaft, lifting members connected to said shaft and dis-.

posed eccentrically thereto, and a carriage I provided with so arated u per and lower earin surfaces t at are a apted to be engaged y said lifting members to cause the carriage and frame to be alternately raised bodily from the ground and moved fory as described. 3. An apparatus of the character described, comprising a frame provided with supporting members that are adapted to the ground, a rotatable shaft carried by said frame and provided with eccentrically disposed lifting members, and bearing surfaces alternately engaged on the carriage cooperating with said lifting members for causing the frame and carriage to be alternately raised from the ground and moved forwardly as the shaft revolves; substantially as described. 7

4. The combination, with a frame having a'shaft and means for turning it, of lifting pins eccentrically connected with the shaft, and a carriage havin side rails that are provided with upper an lower bearing surfaces that are en aged by said pins as the shaft revolves to a ternately lift the frame and car riage away from the und and move them forwardly; substantia ly as described 5. In combination, a frame, a shaft rotatablysupported by the frame and means to turn it, a crank and crankpin carried by the shaft at each end thereof, a skeleton carriage cooperatin with the frame, and a bearing frame on eac side of the carriage in position to receive the crank-pin, the bearing frame having upper and lower interior bearings in position to be alternately engaged by:
